Miscarriage?

So last week I think I may have had a miscarriage, I bled a little heavier and longer than usual but I feel fine other than being super depressed. If someone can please comment and talk to me about their experience with a miscarriage and ask me questions to see if I had one or not would be helpful. I can not get into my dr because they are always booked solid and I don't want to go to the emergency room if it was just an odd period. Thanks in advance
